Proxy Error on https://api-rrd.madavi.de/grafana

I am getting the following error when I try to open the Madavi dashboard for my sensor. Does anyone know whar this is and how to fix it? I really like this page as it gives me graphical representations over time for PM, humidity, temperature, and air pressure but not working for a few days. Note the data does appear to be getting passed through to the maps.sensor.community page. Thanks in advance!

Proxy Error

The proxy server could not handle the request

Reason: Error during SSL Handshake with remote server


Apache/2 Server at api-rrd.madavi.de Port 443

And the ssl certificate is expired too :person_shrugging:

Both should be okay now.
